Application filed February 27, 1585. Serial No. 157,200. I (No model.)

To aZZ whom it 11mg concern.-

Be itknown that I, Orro ZWIETUSOI-I, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of NVisconsin, haveinvented certain new and use ful Improvements in Soda-\Vater Apparatus; and I hereby declare the following to be a full, clear, and exact description of the same.

My various improvements will be the more readily understood by being pointed out in the course of the general description of the apparatus represented in the accompanying drawings, in which Figure l is an end elevation of a soda-water apparatus embodying my improvements; Fig. 2, aplan View of the same; Fig. 3, a vertical section of the valve constituting the gasinlet and water-outlet for the fountains; Fl 4, a vertical section of the screw-cap and valve; Fig. 5, a sectional end view of the agitator and shaft carrying it, taken on the line 5 5 of Fig. 6; and Fig. 6, a longitudinal section of the same.

A is the generator; B, the fountains; O, the acid-head for the generator; .D, thepurifier or washer; E, the pressure gage for the generator; E E, pressure-gages for the fouutains; F," the equalizing-valve or pressure-regulator; G, the pump; H, the gas-dome on the generator; I,the generatoncap and fountain-caps,containing vacuum-valves; J J, the water-gages; K K, the inlets for gas; L L, the outlets for water; M, the siphon filling device; L, the discharge pipe leading thereto; N, the bottling-cylinder, and L the discharge-pipe leading thereto.

The first feature of my improvement lies in theconstruction of the domeI-I on thegcnerator. The purpose of this dome is to prevent the ma terialssuch as marble-dust, whiting, and the like-used for producing the carbonic-acid gas from being carried by a violent ebullition of gas into the pipe which leads from the generator into the washer, and thus producing clogging of the pipe, which may lead to disastrous results. Heretofore I have constructed such domes bottle shapedviz., eylindricalnearly to their tops. I have found, however, that great advantages are obtained by making the dome flaring from top to bottom or conical, as represented in the drawings, since thereby more orless obstruction to the marbledust and other materials used is encountered throughout the whole extent of the dome.

In connection with my various improvements I prefer to adopt as a convenient device the construction of the agitator for the generator shown in detail in Figs. 5 and 6 of the drawings. As heretofore constructed, the agitators have ordinarily been provided with vanes or wings opposite each othera construction which renders the stirring ofthe solid material or sediment in the generator, which adheres closely to the bottom, very difficult and sometimes almost impossible. I overcome all diff culty by providing the agitator with four vanes, each projecting from one side only of the shaft at right angles with the one adjacent to it, the vanes being set so close together as to be practically continuous, whereby a stirring action is exerted during each revolution upon the whole deposit with comparatively little re sistance, only one-fourth of the agitator being in the lower part of the sediment at one time.

For convenience in the construction of my agitator I prefer to provide a shaft, V, square between the journals, and mount upon it wings 'Wrin different directions, as above described, each wing being provided with a square socket at itsinner end, thus permitting it to he slipped upon the shaft and remain fixed in the required direction without danger of turning. In this way, if any wing happens to break or become impaired, it can easily be removed and replaced by another.

The inlets for gas, K, and the outlets for water, L, are placed upon opposite halves of the shell, and are separated to an extent almost equal to the height ofliquid in the fountain, so that the gas will pass through the water to the upper part of the fountain instead of being carried by the water to the bottles while the latter are being filled.

The second feature of my improvement (shown in detail in Fig. 3 of the drawings) lies in the construction which I employ as to the T-shaped stop cocks placed upon the generator, fountains, and elsewhere to regulate the flow of gas and water to or from the pipes,

which are connected to their branches It, extending laterally from the vertical body Q, whereby, first, whether the valve of the stop- IOU cock is open or closed, a free passage for the gas through the branches R is always maintained, and whereby, secondly, the stop-cocks may be easily set with the requisite firmness at any desired angle. The first result 'is effected by having the screw valve-stem c at the point where it enters the horizontal passage through the branches B so slender as not entirely to obstruct the passage, thus permitting the gas to flow through the passage at both sides of the valve-stem even when the valve 0 is forced down upon the seat. The valve, it will be seen, operates to close the vertical passage b in the lower branch,Q,, leading from the lower end of the T-cock to the horizontal passage through the branches R. The valve 0 acts vertically upon the upper end of the passage to open and close it, the valve-stem working in the upper vertical branch, Q, and being operated by a suitable handle, as shown. A convenient way of making the lower portion of the valve-stem sufficiently slender to permit the gas to flow freely by it is by recessing it outjust above the valve, as shown at it. It is also necessary that these stop-cocks be set with their branches R at various angles in a horizontal plane, in order that they may be accommodated to the direction of the pipes connecting with them. Heretofore it has been found a difficult matter to give the stop-cocks the proper direction and at thesame time the requisite firmness and tightness, the position of the horizontal branches having been regulated chiefly by the thickness of the packing and with the aid of aswivel-nut. I overcome this difficulty by means of a screw-collarhaving internal differential screw-threads fitting corresponding differential screw threads on the parts connected by itnamely, the nipple of the fountain or generator and the lower [portion of the vertical stem of the T-cock.

Owing to the difference in pitch ofthe threads, the actual progress ofthe collar when turned is greater along the part having the coarser threads, whichever it may be, than along the part having the finer thread. When the collar is turned in the positive direction, therefore, the coupled parts must eventually come together, when the further turning will produce tension on the collar and corresponding pressure of the coupled parts against each other or against an interposed packing. Thus, for example, a fine thread, F, is provided on the lower vertical branch, Q, of the T cock and the coarser thread, U, on the nipple h of the fountain, the screw-collar S being provided with threads T and U to correspond. It will be seen that by screwing this collar down on the coarse thread the cock is forced against the interposed packing by reason of the differential screw-threads without causing the cock to vary from the direction to which it has been set This construction also insures a tighter joint than can be attained by the ordinary swivel-nut. Constructed as above described, the T-cock is complete in itself. It is easy to manufacture, owing -to the straight passages, and for the same reason it is thoroughly effective and not liable to get out of repair, and, being easy to adjust in whatever position it may be required, it is in every respect perfectly adapted to the purpose for which it is intended.

The third feature of my improvement lies in the construction of the combined cap and vacuum-valve which I employ upon the generator and fountains, and which is shown in detail in Fig. 4 of the drawings. This device is constructed to accomplish. the combined purpose of serving as a cap for the chargingorifice of a generator or fountain,of preventing the collapse of the lining of the same when an internal partial vacuum is produced, and also of letting off the atmospheric air from the interior. The device comprises a cap, it, secured upon the nipple s of the fountain or generator, a vertical tube, r, extending into and above the cap, wholly open at its lower end, and provided with openings (1 at its upper end and with a valveseat, p, in its interior, andavalvestem, 0, carrying a valve, n,which acts upward against the valve-seat, and hasa knob, P, upon its upper end. The valve is normally open and allows the atmospheric air contained in the generator or fountain to escape until a certain low pressure of gas is attained, when the valve is automatically closed by the pressure. If a further escape of air or of gas is desired, this may be effected by pressing down upon the knob. pended entirely from the knob P and opens by gravity alone, everything which might tend to create friction or impede the action of gravity being excluded from the construction. I avoid the use of separate openings for the attachment of the water-gages J by connecting them at the top to a branch pipe, 00, leading horizontally from the nipple s and at the bottom to a branch pipe leading into the pipe 1, which also serves as the inlet for water from the pump, as represented in Figs. 1 and 2 of the drawings, whereby each opening in the fountain is caused to effect a twofold purpose.

The fourth feature of my improvement lies in the construction which I employ for utilizing in the fountain the residue of gas in the generator after the chemical action of the ingredients therein has grown so feeble as to render recharging necessary. Heretofore it has been the practice when recharging became necessary to shut off communication between the generator and fountains and empty the generator of its contents, inclusive of the gas, which was thus wasted. I avoid this waste by providing the pump G with a second suctionpipe, K, leading from the washer D. If the pump is to be used for pumping water against pressure, the stop-cocks o and g in the gas-sue tion pipe are closed and the cock (1 in the water-suction pipe is opened, thus filling the fountain with water under pressure. If gas is to be pumped, the cock d in the water-suction pipe and the gas-cock f in the pipe which leads from the washer to the fountains are closed and the gas-cocks 0 and g opeued,where- It will be seen that the valve is sus eereve by the action of the pumps is exerted upon the gas in the generator instead of upon the water, and thus gas from the generator in place of water is forced by the pump into the fountains B. It is to indicate the pressure thus produced that the fountains are provided with separate pressure-gages E. The operation is suspended when the gage E shows that all the gas has been abstracted from the generator, and the latter is then in a condition to be recharged without loss. To raise the pressure in the fountains higher than that eontainedin the generator and purifier, the pump is worked in the same manner.

The fifth feature of my improvement consists in combining with the soda-water fountains or receiver an equalizing -valve, F, located between the fountains and the bottlingcylinders. The equalizing-valve which I prefer to employ is described in Letters Patent No. 187,446, granted to me February 13, 1877 5 but other forms in common use may be used instead. It is not new to use such a valve in connection with soda water apparatus; but heretofore, as far as I am aware, it has always been located between the generator and the fountains, and in that situation it will not perform the functions which I desire. By placing it, as shown, in the discharge-pipe L", between the fountains and bottling-cylinders N, aeertain pressure lower than that in the founta-i'ns may at all times be kept on the bottles to be filled without reference to the actual pressure in the fountains. Thus, for example, a pressure of one hundred and twenty five pounds may be contained in the fountains, (whichisasuitablcpressureforfillingsiphons,) and the regulator, fastened to another outletpipe leadingto a filling-machine, may be set to any lower pressure suitable for the purpose. In this way bottles at N may be filled at, say, sixty pounds pressure through the pipe L, while the siphons at M are at the same time being filled at the full pressure of the fountains through the pipe L. The regulating valve thus placed in the dischargepipe between the fountain and the bottling cylinder is operated by the pressure in the receptacles undergoing the process of filling under the bottling-cylinder in such manner as to check the passage of liquid from the fountain when, preceding the closure under pressure of the receptacles, a predetermined pressure has been reached therein.

The regulator is so arranged as to cutoff the supply as soon as a predetermined pressure exists in the discharge-pipe beyond the regulater and distant from the source of supply. To illustrate the action, suppose the regulator to have been set at thirty pounds. The bottle being introduced below the fillingcylinder and the supply-valve opened, a pressure equal to the thirty pounds arises in the bottle be fore it is filledwith the requisite quantity of liquid; but the regulator cuts off all further supply until" the pressure beyond the regulator is reduced below thirty pounds. Most filling heads are provided with an eseape-valve in the nature of a safety-valve. If this valve be set to, say, twenty-nine and one-half pounds, the atmospheric air in the bottle will escape and make room for the liquid, which continues to flow as long as the pressure in the bottle remains below thirty pounds. In other cases no safety-valve is provided and the desired relief and escape of air are obtained by lifting the filler-head from the bottle, or vice verse. In this case the liquid flows until the pressure of thirty pounds is established in the bottle, and if the latter is not then filled the filler-head has to be eased again, in order to allow an escape of air or gas and a reduction of pressure and consequent filling of liquid to the desired level. The bottle is then stoppered while under this pressure without previous removal from the filler-head.
